602520 ÷ 12 
We want to divide 602520 by 12.

On to step 1:
If we divide 6 by 12, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 12

Let's proceed to step 2:
When dividing 60 by 12, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 60 from 60 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 12

On to step 3:
The number 12 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 50.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 12

Moving on to step 4:
12 goes into 25 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 502.0
The remainder is 1 after subtracting 24 from 25.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 12

Let's proceed to step 5:
12 divided by 12 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 5021.0
Subtracting 12 from 12 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 12

Advancing to step 6:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50210.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 50210.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 50210.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 50210.0 with a remainder of 0.0.
